Remove The Cols And Rows Attributes?

Oct 23, 2010

i have a asp:TextBox control on the page. i'm setting it to a TextMode="MultiLine", I am not setting a number of rows or columns. I am setting a width and height in CSS for the control.

asp.net is still adding, what i assume is a default, rows and cols attributes on the rendered control. cols="20" and rows="2" this isnt an issue in any sane, browser, but in IE the CSS height is ignored and only 2 rows of space is show.

How can I prevent these attributes from showing up on the rendered control?

Edit:

This is an issue only in IE8 in compatibility mode, IE7 and IE6. I'm not worried about IE6, but IE7 needs to work.

Forms Data Controls :: Gridview Save Existing Data When Adding Rows Via Arraylist?

Jan 19, 2010

I have a gridview that contains template fields with textboxes that is used to look up inventory items. The page loads using an arraylist to display a gridview control with a predetermined number of rows. There is also drop down control that allows the user to add additional rows to the gridview if needed.

Currently when a user has already entered some data if you use the drop down to add more empty rows all the original entrys are removed. I want to save the original data and then add empty rows at the end.

>>

Private Sub LoadDataGrid(ByVal numberOfRows As Integer)
Dim Counter As Integer
Dim GridList As New ArrayList
For Counter = 0 To numberOfRows
GridList.Add(New LibVB.Form2VB(Counter))
Next
gvEnterParts.DataSource = GridList
gvEnterParts.DataBind()
End Sub
<<

I'm lost, kind of a newbie to .net, have been working on this for 2 days! d.

Forms Data Controls :: Failed To Load Viewstate When Gridview Control - Replace Gridview With Datagrid

Apr 5, 2010

Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request.

The above error occurs with gridview control , when used with template field columns with item template / and edit templates etc.
updating a row within gridview, at the time of loadiong it loads perfectly fined, but when tried to modify an existing row within gridview control, then it produces the error. Make sure the grid view control has to be a child control which manages the child table info with in a master form. to reproduce the above problem the grid view must be loading the child records info of a master within the masterform, meaning both master data and gridview data all to be managed in one single form.

I had to replace gridview control with datagrid and then it worked perfectly fine. I wasted almost 4 days of my time., there is no way we could figure out the problem. here is the full info of the problem.

Page Throws ViewState Error When Items Collection Of Dropdownlist Is Modified In IndexChanged Event

Feb 25, 2011

I have an ASCX control which is a special dropdownlist. I add that control dynamically to the page and fill it with data. This control has a postback that will change the contents of a second dynamically created standard dropdownlist.

When I change the selection on the first dropdown, the indexchanged fires and I get new data and attempt to place it in the second dropdownlist's items collection, by first clearing it then filling it with new data.

This works fine the first time a change the selection, but when I select a second time the following error is thrown:

The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request.

I'm not adding or removing new controls in the fired event, only changing data. And again, it works the first time, but doesn't subsequent times.

If I disable stateview on the child control, then the control just doesn't get updated with data at all.

Forms Data Controls :: Dynamic GridView ViewState Not Preserved?

Apr 22, 2010

I am creating a gridview dynamically in a custom control and adding it to a Panel. I set the EnableViewState = true. The problem is that on a page postback the GridView does not seem to retain its values. If I add a GridView through the UI then the viewstate is preserved. The problem seems to occur when it is put dynamically only.
